New to ASCIIDocs–wondering if there is an easy way to add text (a single centered word) before the book title.

I would place the following regexp: ^(?!s)[^0-9!#|$^`\~_%&"'(){}*+,./:;<=>?@][]*(?<!s)$ in the ASCII doc table.

I want to set the keywords attribute based on the hierarchy of sections.

The title says it all. I have been reading through all of the documentation I can find and I can’t find any distinction between the two.
